In a prior blog post, I talked about latency analogies.  I compared levels of latencies to your home, your neighborhood, a far-away neighborhood, and another city.  I talked about these localities in terms of communication.

Let’s extend that analogy to talk about data locality.

OpenDaylight: Understanding the Value Propositions

April 8, 2013 at 6:03 am PST

The announcement today of OpenDaylight is big news.  Industry leading companies are partnering via Open Source to serve an emerging set of market needs:

  • Operators: want affordable real-time orchestration and operation of integrated virtual compute, application, and network.
  • Application Developers: want a single simple interface to the network.  Underlying details such as “router”, or “switch”, or “topology” can be a distraction they desire to abstract and simplify away.
  • Equipment Vendors: want a stable forum to interwork a plethora of Application interfaces with a plethora of nascent Network Device programmatic interfaces.

Cisco Partners with Industry-Leading Trade Monitoring Vendors to Give High Performance Traders Enhanced Visibility

Today, April 8, 2013, the brightest of Wall Street are meeting at the 10th Annual High Performance Computing Linux for Wall Street event in New York to learn about the latest technology innovations that give financial trading firms a competitive edge. With network latency achieving speeds of less than 50 nanoseconds, this year’s event focuses not only on speed but also on cutting-edge advances in network visibility, analytics and instrumentation. One way Cisco is helping traders gain a competitive edge in this area is by offloading the gathering of analytics data to the network devices, and working with industry leading monitoring firms like Corvil and TS-Associates to decode these new sources of data.

No doubt, high performance trading systems are becoming faster, processing more data than ever before. Network performance is of paramount importance in high performance trading markets where obtaining and acting on real-time equities, options and other financial market information, nanoseconds faster than competitors, may be worth millions of dollars. While complex trading analysis and risk mitigation still need to be performed outside the network layer, significant cost savings and scale advantages can be obtained by leveraging embedded intelligence in the network to enable key functions such as fabric congestion monitoring and intelligent traffic mirroring.
